can any one suggest me how can i resolve this problem?

Hi Uday,
My guess is that there is a problem with your java stored procedure that is causing the "ExceptionInInitializer" error to be thrown. According to the javadoc:
is thrown to indicate that an exception occurred during
evaluation of a static initializer or
the initializer for a static variable
Since I didn't see any of your code in your post, I can't help you much more, I'm afraid. Perhaps if you would provide some more details, I may be able to help you some more. I think the following details would be helpful:
1. Complete error message and stack trace you are getting.
2. The section of your java code that you think is causing the problem.
3. Oracle database version you are using.
Good Luck,
Avi.

Error while executing java stored procedure from a pl/sql procedure

We have a requirement where we need to execute JAVA code stored in an Oracle database (Java Stored Procedure). This code uses some JAR files which we have already loaded without any errors in the database.
The class file was also loaded in the database without any errors. But when we execute the method of this class (JAVA code), it gives the following error:
ORA-29532: Java call terminated by uncaught Java exception:
java.lang.NoClassDefFoundError
Is there any way of debugging the code and getting to know where exactly the problem is? Or, any tool/software available for doing the same.
Any pointers would be of great help!
Thanks in advance

NOTE: I don't work with JDBC/jConnect so (at this point) just some questions ...
1 - are you sending this to ASE, ASA, IQ, or some other RDBMS?
2 - what is the value of <schemaname>?
3 - do you have other prepareCall() instances that successfully call a stored proc? [would be interesting to see if there's a difference in the format of the calls]
A quick google search shows a couple ways to submit a stored proc execution to the RDBMS, with the format depending on the format expected by the target RDBMS.
I'm wondering if you really need/want the parentheses around the argument list, ie, what happens if you change
from
-- parentheses around args
EXEC <dbName>.<schemaName>.<SPName> ( ?,?,?,?,?,...,? )
to
-- no parentheses around args
EXEC <dbName>.<schemaName>.<SPName> ?,?,?,?,?,...,?
In ASE if I wrap the parameters in parentheses I get the same error you're getting:
================== w/ parentheses => error
1> sp_who (sa)
2> go
Msg 102, Level 15, State 1:
Server 'CC1_V1', Line 1:
Incorrect syntax near 'sa'.   <<=== sa == @p0 ??
================== w/out parentheses => works
1> sp_who sa
2> go

Error while executing a stored procedure from forms6i

When I execute a STORED PROCEDURE from ORACLE DB 10g this procedure works perfectly fine.
But when I execute the same from the FORMs 6i I get the following error:
PDE-PLU022 Don't have access to the stored program unit
XMLPARSERCOVER in schema CARE.
where XMLPARSERCOVER is the class and
CARE is the schema.
Regards,
Jignesh S

I have tried this with both the owner of the schema and the intended user, -from both forms and directly.
All rights was granted on the stored procedure. Since posting I have found that one of the tables that the procedure might insert into, was not explicitly granted to the intended user, and after rectifying that the error message went away.
-however, the procedure now silently "finishes" without any evidence that it ever ran, if invoked from the forms application. When invoked from SQL Plus (or JDev, or Toad) it runs as expected.
I have no public synonym for the procedure, -is that necessary?
The stored procedure in question is implemented in java, and published as a stored procedure. It does rather heavy lifting, when running, using a view against another server , updating local tables and quite a lot of data validation/cleansing, and logging. All recourses are within the same schema.
Any ideas?

Error ORA-04031 while executing a stored procedure from Pro C++ code

I am getting the error ORA-04031(Unable to allocate 4096 bytes of shared memory("Shared Pool",.....)) while trying to execute a stored procedure from my pro*C application. This happens only after a few hours since the application has been running. I am closing the cursor after every database call.
Does anyone know why it is happening and any possible solutions?
TIA
Srithaj.

One thing that can be done is to flush the shared pool before starting the application.
alter system flush shared pool;
Another is to increase the shared pool size by setting the parameter shared_pool_size in init_sid.ora file.

Geeting TIMEOUT while executing a Stored Procedure.

Hi Gurus,
Am facing a TimeOut issue while executing the Sql Stored Procedure.
I have changed a settings of Execution TimeOut to Zero (which is unlimited ), Am still unable to execute the Stored Procedure.
Should i have to add any TimeOut Command in my Sql Stored Procedure. If please suggest me.
Thanks in advance.

Time out is the client who throws the error not SQL Server. Please read Erland's article
http://www.sommarskog.se/query-plan-mysteries.html
Are you sure there is blocking/locking? Is that possible someone run BEGIN TRAN and did not properly specify COMMIT TRAN?

21700 while calling java stored procedure in 9i

I create a java stored procedure that takes a varray of a rowtype. When I call that procedure, I get an ora-21700. If I remove the varray from the parameter list, I can call the procedure okay. My goal is to create a generic java procedure that can take a rowtype from any table and create XML. Once I get the oracle.sql.ARRAY into my code, I am okay. I just can't seem to pass it in. I have pasted my code below:
Java:
import oracle.sql.*;
public class test {
public static String sayHello() {
return("Hello, World!");
public static void genXML(oracle.sql.ARRAY a, oracle.sql.CLOB c) throws Exce
ption {
c.putString(1,"<test>This is a test!</test>");
PL/SQL:
create or replace package mike is
type dummy_record is varray (1) of dummy%rowtype;
PROCEDURE GENERATE_XML(i dummy_record, c CLOB);
FUNCTION SAYHELLO RETURN varchar2;
end mike;
show errors
create or replace package body mike is
PROCEDURE GENERATE_XML(i dummy_record,c CLOB)
AS LANGUAGE JAVA
NAME 'test.genXML(oracle.sql.ARRAY,oracle.sql.CLOB)';
FUNCTION SAYHELLO RETURN varchar2
AS LANGUAGE JAVA
NAME 'test.sayHello() return java.lang.String';
end mike;
show errors
DDL:
SQL> describe dummy
Name Null? Type
USERNAME VARCHAR2(20)
ID NUMBER
Test Script:
declare
m Mike.dummy_record := Mike.DUMMY_RECORD();
c CLOB;
begin
m.extend;
select xml into c from t_clob;
for rec in (select * from dummy)
LOOP
m(1) :=rec;
mike.generate_xml(m,c);
end loop;
end;
And finally, the output:
declare
ERROR at line 1:
ORA-21700: object does not exist or is marked for delete
ORA-06512: at "MMANGINO.MIKE", line 0
ORA-06512: at line 10
Sorry this post is so long, but I wanted it to be complete!
Mike

The first solution is to not do that in java in the first place.
DDL should be in script files which are applied to oracle outside of java.
Other than I believe there are some existing stored procedures in Oracle that take DDL strings and process them. Your user has to have permission of course. You can track them down via the documentation.

Hi,
Try this
CREATE OR REPLACE PROCEDURE skeleton1

Problem while executing a Stored Procedure

Hi,
im a newbie,using Oracle 10g v(10.2.0.1.0) on linux machine.
Im unable to execute following procedure through iSQLPLUS query interface.
create or replace procedure pd_hr(
pno varchar2,
pdt date default sysdate,
phr out number,
perr_msg out varchar2
) as
begin
phr := 2;
end pd_hr;
VARIABLE phr number;
VARIABLE perr_msg VARCHAR2(250);
execute pd_hr('pno',NULL,phr,perr_msg);
It flashes the following error when i try to execute the stored proc:
ERROR at line 1:
ORA-06550: line 1, column 44:
PLS-00201: identifier 'PHR' must be declared
ORA-06550: line 1, column 7:

I executed the following query through DBA login before executing the procedure:
GRANT EXECUTE ANY PROCEDURE TO "SCOTT";
Any kind of assistance will be priceless!

Hi, Peter,
user10707566 wrote:
Thanks Frank, it worked seamlessly!
btw what the ':' signifies here?":" just means "this is a bind variable".
It's convenient, because when you name a bind variable "phr", you can use ":phr" without worrying whether there is a column or a local variable that is also called phr, and, if so, which one takes precedence.

Executing batch file from Java stored procedure hang

Dears,
I'm using the following code to execute batch file from Java Stored procedure, which is working fine from Java IDE JDeveloper 10.1.3.4.
public static String runFile(String drive)
String result = "";
String content = "echo off\n" + "vol " + drive + ": | find /i \"Serial Number is\"";
try {
File directory = new File(drive + ":");
File file = File.createTempFile("bb1", ".bat", directory);
file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
fw.write(content);
fw.close();
// The next line is the command causing the problem
Process p = Runtime.getRuntime().exec("cmd.exe /c " + file.getPath());
BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line = input.readLine()) != null)
result += line;
input.close();
file.delete();
result = result.substring( result.lastIndexOf( ' ' )).trim();
} catch (Exception e) {
e.printStackTrace();
result = e.getClass().getName() + " : " + e.getMessage();
return result;
The above code is used in getting the volume of a drive on windows, something like "80EC-C230"
I gave the SYSTEM schema the required privilege to execute the code.
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'java.io.FilePermission', '<<ALL FILES>>', 'read ,write, execute, delete');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
GRANT JAVAUSERPRIV TO SYSTEM;

I have posted this in JDeveloper forum ([t-853821]) but suggested to post for forum in DB.
Can anyne help?

Dear Peter,
You are totally right, I got this as mistake copy paste. I'm just having a Java utility for running external files outside Oracle DB, this is the method runFile()
I'm passing it the content of script and names of file to be created on the fly and executed then deleted, sorry for the mistake in creating caller function.
The main point, how I claim that the line in code where creating external process is the problem. I have tried the code with commenting this line and it was working ok, I made this to make sure of the permission required that I need to give to the schema passing security permission problems.
The function script is running perfect if I'm executing vbs script outside Oracle using something like "cscript //NoLogo aaa1.vbs", but when I use the command line the call just never returns to me "cmd.exe /c bb1.bat".
where content of bb1.bat as follows:
echo off
vol C: | find /i "Serial Number is"
The above batch file just get the serial number of hard drive assigned when windows formatted HD.
Same code runs outside Oracle just fine, but inside Oracle doesn't return if I exectued the following:
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
Never returns
Thanks for tracing teh issue to that details ;) hope you coul help.
